RAK4200 and Chirpstack Frame counter

Issue: I have 5 sets of RAK4200-based devices. Rak4200 modules are connected to the chirpstack gateway running on the RAK5146 concentrator. Currently, devices are running on ABP mode. and I have disabled the frame counter validation. After reaching the downlink frame counter around 20000 in the Chirpstack server, Uplink messages from Rak4200 are rejected by the Gateway. I have to manually clear the uplink and downlink counter and reactivate it in order to receive the messages. Is there a method to clear the counter via python script or via MQTT? or any other method to overcome the issue?

Thank you in advance.

That is a question for the Chirpstack forum. Did you check there?
